Method Detail

getId

public int getId()

Return spatial reference ID.

Returns:

spatial reference ID

getDefinitionString

Returns spatial reference definition string.

Returns:

spatial reference definition string

getType

public int getType()

Returns spatial reference type.

Returns:

spatial reference type

getWebSpatialReference

public static WebSpatialReference getWebSpatialReference(int id)

Returns an instance of WebSpatialReference corresponding to its ID.

Parameters:

id - id of the spatial reference

Returns:

an instance of WebSpatialReference

getWebSpatialReference

public static WebSpatialReference getWebSpatialReference(String definitionString)
